Figured out the first two, but I don't understand how to use Euler's method on this problem. Can you help with that?

Homework Statement Newton's Law of Cooling states that the rate of cooling of an object is proportional to the temperature difference between the object and its surroundings. Suppose t is time, T is the temperature of the object, and Ts is the surrounding temperature. The following...

Homework Statement To complete your master's degree in physics, your advisor has you design a small, linear accelerator capable of emitting protons, each with a kinetic energy of 8.2 keV. (The mass of a single proton is 1.67 x 10^-27 kg.) In addition, 1.00 x 10^9 protons per second must reach...

Thanks for the response but I don't quite understand what you mean by setting up two integrals? Could you explain it to me? Also I could still use help for the second problem. Thanks a lot!

Hey guys, I have a couple of problems about hydrostatic force and center of a mass that I was hoping someone could help me out with. Center of mass Homework Statement Sketch the region bounded by the curves y=2x^3, x+y=3 and y=0. Find the coordinates of the centroid. Homework Equations Sorry I...

Wow thank you very much! I finally figured them both out! Thank you once again!

Ok got it, thanks! But can someone help me out with the second problem too?

Hey all, I've been lurking for a while to try and see if these problems were solved already but I couldn't find anything so here I am posting! Question #2:A ball is thrown straight upward from the ground. The ball passes a window 4.35 m above the ground and is seen to descend past that same...
